Hi Leigh,

I think something like around 6.5/10 from what I can see in your image. See a video might help. Above average seeing can often be confused with really good seeing, especially when it is fairly ordinary most of the time.

This is a link to a portion of my Red channel in 2008. You can see Io very close to the border between the NEB and EQ Belts just slightly right of centre. At moments the detail just starts to pop. That I consider to be about 8-8.5/10

Damian Peach has a really good Pickering Scale example in the link below.

Damian is still the master of all masters. He continues to produce great images even with the 1 metre telescope in Chile.
